Cloud Security Alliance Updated CCSK Exam Questions and Answers by ettie

The division of security responsibilities changes according to the service model. In IaaS, CSCs handle more security responsibilities, while in SaaS, the CSP manages more of the security aspects. Reference: [Security Guidance v5, Domain 1 - Shared Responsibility Model][17†source].

A Web Application Firewall (WAF) is primarily responsible for filtering and monitoring HTTP/S traffic to and from a web application. It is designed to protect web applications by filtering and monitoring traffic for malicious requests, such as SQL injection, cross-site scripting (XSS), and other common application-layer attacks. A WAF helps secure web applications by analyzing the HTTP/S traffic and blocking any harmful requests before they reach the application.

Anti-virus Software is used to detect and remove malicious software on endpoints and devices but is not designed to filter HTTP/S traffic specifically for web applications. Load Balancer is used to distribute network traffic across multiple servers to ensure performance and reliability, but it does not focus on security filtering. Intrusion Detection System (IDS) monitors network traffic for suspicious activity but operates at a different level of the network stack and is not focused solely on web application traffic.

A cloud workload refers to the application software or services that are deployed and run on cloud infrastructure or platform. It can include a variety of computing tasks such as processing data, running applications, or performing computations, depending on the type of workload. Cloud workloads are typically virtualized and managed within cloud environments, utilizing resources like compute, storage, and networking provided by the cloud infrastructure or platform.

A network of servers connected to execute processes refers more to the underlying infrastructure, not the workload itself. A collection of physical hardware used to run applications describes the infrastructure, not the workload. A single software application hosted on the cloud is a partial description but doesn’t capture the broader concept of workloads, which could include multiple services or applications.

In the context of server-side encryption handled by cloud providers, the data is encrypted after transmission to the cloud using either provider-managed keys or customer-managed keys. The cloud provider takes responsibility for encrypting the data when it is stored in the cloud, ensuring that the data at rest is protected.

Server-side encryption typically uses symmetric encryption for performance reasons, but this attribute is not what defines the encryption process. Also, server-side encryption focuses on protecting data once it's in the cloud, not before transmission. Encryption in transit is typically handled separately from server-side encryption and applies to data as it moves between the client and the cloud.
